Digital v Film Cameras: printing pixelation
October 17th 2007 03:50
selection of digital cameras
There are considerable differences between 'film' photography and digital photography, although most nowadays rely on assistance from computers, thus making both digital, so to speak, but a word is coined to have a specific application and the 'takeover' proceeds unchallenged.
Digital imaging, as it is known, uses an electronic image sensor to record the image as a set of electronic data rather than as chemical changes on film.
Because of this, digital photographs are much more prone to manipulation than are film, which resist such abuses. In the courts Judges will not accept digital images as evidence.
professional photographers have their own practices to adhere to when using these images but I don't think there will be too many professional photographers reading this blog. But some of the things that relate to professional photography will be of benefit to the amateur or semi- professional so those considerations will not be dismissed.
For the average photographer the use of digital cameras has far outstripped the use of film.
pixelation
I prefer film photography for a variety of reasons, some technical, some personal, but we need to understand that the usual requirement in the market place is for digital and we shall fast be facing a generation who relegate (unwisely) film photography as some antiquated technique, sadly.
All photography has various uses which need to be met, from technical images to sophisticated art forms.
I'll perhaps do a post on those various aspects another day.
Film images can be converted to digital images using a scanner.
Converting film to digital using a scanner
So how do you turn the images in your digital camera into printed photos?
You have 3 options:
You can do it:
At home
Online
At the store
You need software and a digital cable to move images from your camera to your computer and after that you can print them with your printer.
The software, and there are choices, is usually available for free.
or, for the store, make sure their equipment is compatible with your digital camera and software program.
1 - Find a store with Picture Maker.
2 - Take your digital camera memory card, CD, or disk to the store.
3 - Follow the on-screen instructions to print your pictures.
If you're stuck, ask the store owner to help you and once you become familiar with what is required you can confidently do it yourself.
You may not get the same quality in the printed product as you are expecting but things are improving and a lot depends on your particular camera.
very bad pixelation
Many people just keep the images in their camera and don't go beyond that.
If you're wanting to know how to get good prints you need to talk in terms of pixels.
Pixels are the tiny little squares or dots of which digital images are composed.
So how many pixels do I need?
Good resolution
It is not that simple as other factors come into play, but as a general rule the best thing to do is to choose a camera with a resolution (the little squares or dots) which suits your needs.
Printed images need generally 150 dots per inch (dpi). But sometimes depending on a number of factors you will still see signs of pixelation which of course spoils your image. So, do remember that there are other factors that can affect the minimum resolution and the quality of the printed product.
So, there are circumstances where bigger is definitely not better.
Really good digital image
Many would argue that digital cameras are better than film.
In fact, a digital camera is better quality than a film camera in many important respects! A 35mm film-based camera will beat any digital camera in resolution. But if you care about color balance under mixed lighting or scale, a digital camera may be better than a film camera.
Your best bet is to choose a camera with a resolution appropriate for your needs.
